Abstract

Ein hydropneumatisches Federelement für Fahrzeuge, insbesondere Kettenfahrzeuge, sowie eine Laufradaufhängung an einem Kettenfahrzeug mit einem derartigen Federelement. Das Federelement besitzt einen ersten Zylinder (1), der ein hydraulisches Dämpfungsglied (6) sowie einen ersten Abschnitt (4) einer Ölkammer und einen Teil einer Ölvorratskammer (7) enthält. In einem parallel zum ersten Zylinder (1) angeordneten zweiten Zylinder (1') sind ein zweiter Abschnitt (4') der Ölkammer, der Trennkolben (5) und die Gaskammer (3) angeordnet. Der erste Zylinder (1) ist mit dem zweiten Zylinder (1') über ein Verbindungselement (10) verbunden, welches eine hydraulische Verbindung (10.1) zwischen dem ersten Abschnitt (4) und dem zweiten Abschnitt (4') der Ölkammer enthält. Im ersten Zylinder (1) ist ein dritter Zylinder (2) teleskopartig und dichtend geführt, der den restlichen Teil der Ölvorratskammer (7) enthält. Durch eine Verschiebung des ersten Zylinders (1) und des dritten Zylinders (2) gegeneinander ist der Rauminhalt der Ölvorratskammer (7) veränderbar. Durch diese Anordnung lässt sich eine starke Baulängenverkürzung des Federelements erreichen, so dass es auch bei kleinem Einbauraum an der Laufradaufhängung eines Kettenfahrzeugs einsetzbar ist.

Figure imgaf001
A hydropneumatic spring element for vehicles, in particular tracked vehicles, as well as an impeller suspension on a tracked vehicle with such a spring element. The spring element has a first cylinder (1) containing a hydraulic damping member (6) and a first portion (4) of an oil chamber and a part of an oil reservoir chamber (7). In a parallel to the first cylinder (1) arranged second cylinder (1 '), a second portion (4') of the oil chamber, the separating piston (5) and the gas chamber (3) are arranged. The first cylinder (1) is connected to the second cylinder (1 ') via a connecting element (10) which contains a hydraulic connection (10.1) between the first section (4) and the second section (4') of the oil chamber. In the first cylinder (1), a third cylinder (2) is telescopically and sealingly guided, which contains the remaining part of the oil reservoir chamber (7). By a displacement of the first cylinder (1) and the third cylinder (2) against each other, the volume of the oil reservoir chamber (7) is variable. By this arrangement, a strong length shortening of the spring element can be achieved, so that it can be used even with a small installation space on the wheel suspension of a tracked vehicle.
